Audio in streamed to network?

I am trying to figure out if it’s possible to take analog audio input, digitize the input and stream it thru a lan? I would like to use an arduino if possible or a Pi.

The idea being that I could monitor the audio in the barn while I’m in the house eating.

From what I’m seeing on the forums it might be asking too much of the Atmel processor.

Thoughts, ideas, solutions??

Thanks
